Abstract:
A mobile communication device comprises a plurality of receivers, a phase detection circuit, and a DC offset calibration circuit. Each receiver comprises a receiver chain and a divide-by-2 circuit that supplies Local Oscillating (LO) signal for the receiver chain. The LO signals leak to each receiver chain and create an undesirable DC offset voltage. The DC offset depends on an LNA gain and a phase relation among the LO leakages. In a first novel aspect, a two-dimensional DC offset calibration (DCOC) table is prepared for each receiver chain. In a second novel aspect, the phase detection circuit detects the phase relation among the LO leakages for each receiver chain. Based on the LNA gain and the detected phase relation of each receiver chain, a DCOC code is selected from a corresponding DCOC table such that the calibration circuit calibrates the DC offset for each receiver effectively and efficiently.
